Welcome to NeuroTalk!
I don't have that problem but my brother in law does. His started at about your age too. He also has rheumatoid arthritis but I don't know how or if the two are connected.
He keeps exercising (like you) and stays pretty active despite what he deals with as far as symptoms go.
There's a forum here for peripheral neuropathy:

Check it out, there's lots of information there and lots of nice folks on the forum as well. Take care.
